How was Marco Polo's route to China different from his return route home?

The journey from China to Persia was the most dangerous of their journey. Only 18 people of the original 600 survived. After arriving in Persia they took off overland for Europe. During their trip across Iran they were robbed of some of their gold and jewels

Explanation:

According to the Silk Road Foundation: “Marco did not provide full account of his long journey home. The sea journey took 2 years during which 600 passengers and crewed died. Marco did not give much clue as to what went wrong on the trip, but there are some theories. Some think they may have died from scurvy, cholera or by drowning; others suggest the losses were caused by the hostile natives and pirate attacks. This dreadful sea voyage passed through the South China Sea to Sumatra and the Indian Ocean, and finally docked at Hormuz. There they learned that Arghun had died two years previously so the princess married to his son, prince Ghazan, instead. In Persia they also learned of the death of Kublai Khan. However his protection outlived him, for it was only by showing his golden tablet of authority that they were able to travel safely through the bandit-ridden interior.
